Cache Discovery Protocol
The Cache Discovery Protocol (CDP) is an extension to the BitTorrent file-distribution system. It is designed to support the discovery and utilisation of local data caches by BitTorrent peers, typically set up by ISPs wishing to minimise the impact of BitTorrent traffic on their network. The Cache Discovery Protocol was originally developed jointly by BitTorrent, Inc. and CacheLogic and first implemented in version 4.20 of the official BitTorrent client, released June 22, 2006. However, despite claims that the details of the protocol would be published, to date no specification has been made publicly available.

Web Cache
A Web cache (or HTTP cache) is a system for optimizing the World Wide Web. It is implemented both client-side and server-side. The caching of multimedias and other files can result in less overall delay when browsing the Web. Parts of the system Forward and reverse A forward cache is a cache outside the web server's network, e.g. in the client's web browser, in an ISP, or within a corporate network. A network-aware forward cache only caches heavily accessed items. A proxy server sitting between the client and web server can evaluate HTTP headers and choose whether to store web content. A reverse cache sits in front of one or more web servers, accelerating requests from the Internet and reducing peak server load. This is usually a content delivery network (CDN) that retains copies of web content at various points throughout a network. HTTP options The Hypertext Transfer Protocol (HTTP) defines three basic mechanisms for controlling caches: freshness, validation, and invalidatio ...

Internet Service Providers
An Internet service provider (ISP) is an organization that provides services for accessing, using, or participating in the Internet. ISPs can be organized in various forms, such as commercial, community-owned, non-profit, or otherwise privately owned. Internet services typically provided by ISPs can include Internet access, Transit (Internet), Internet transit, domain name registration, Web hosting service, web hosting, Usenet service, and colocation centre, colocation. An ISP typically serves as the access point or the Default gateway, gateway that provides a user access to everything available on the Internet. Such a network can also be called as an eyeball network. History The Internet (originally ARPAnet) was developed as a network between government research laboratories and participating departments of universities. Other companies and organizations joined by direct connection to the Internet backbone, backbone, or by arrangements through other connected companies, so ...

BitTorrent, Inc
Rainberry, Inc., formerly known as BitTorrent, Inc., is an American company that is responsible for the ongoing development of the BitTorrent peer-to-peer protocol, as well as the ongoing development of μTorrent and BitTorrent Mainline, two clients for that protocol. Files transferred using the BitTorrent protocol constitute a significant slice of all Internet traffic. At its peak, 170 million people used the protocol every month, according to the company's website. The company was founded on September 22, 2004 by Bram Cohen and Ashwin Navin. In 2018, the company was acquired by cryptocurrency startup TRON, and Bram Cohen left the company. BitTorrent protocol software BitTorrent is a peer-to-peer computer program developed by Bram Cohen and BitTorrent, Inc. that is used for uploading and downloading files via the BitTorrent protocol.

BitTorrent (software)
BitTorrent is a proprietary adware BitTorrent client developed by Bram Cohen and Rainberry, Inc. used for uploading and downloading files via the BitTorrent protocol. BitTorrent was the first client written for the protocol. It is often nicknamed Mainline by developers denoting its official origins. Since version 6.0 the BitTorrent client has been a rebranded version of μTorrent. As a result, it is no longer open source. It is currently available for Microsoft Windows, Mac, Linux, iOS and Android. There are currently two versions of the software, "BitTorrent Classic" which inherits the historical version numbering, and "BitTorrent Web", which uses its own version numbering. History Programmer Bram Cohen designed the protocol in April 2001 and released a first implementation of the BitTorrent client on 2 July 2001. It is now maintained by Cohen's company BitTorrent, Inc. Prior to version 6.0, BitTorrent was written in Python, and was free software. Very early versions release ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Web Cache Communication Protocol
Web Cache Communication Protocol (WCCP) is a Cisco-developed content-routing protocol that provides a mechanism to redirect traffic flows in real-time. It has built-in load balancing, scaling, fault tolerance, and service-assurance (failsafe) mechanisms. Cisco IOS Release 12.1 and later releases allow the use of either Version 1 (WCCPv1) or Version 2 (WCCPv2) of the protocol. WCCP allows utilization of Cisco Cache Engines (or other caches running WCCP) to localize web traffic patterns in the network, enabling content requests to be fulfilled locally. Traffic localization reduces transmission costs and download time. Protocol Versions WCCPv1 * Only a single router services a cluster of systems * Supports HTTP ( TCP port 80) traffic flows only * Provides generic routing encapsulation (GRE) to prevent packet modification * Routers and cache engines communicate to each other via a control channel based on UDP port 2048 WCCPv2 * Allows for use across up to 32 routers (WCCP ser ...
